Letters Patent No. 106,087, dated-August 2,1870.

To all whom it may concern; a y

Be known that I, FRANKLINR, Shirt], of Ilion, in the county ofHerkimerand State of New York,

have invented a ne'wand improved Hay-Tedder; and

I do hereby declare the following, when taken in connection with theaccompanying drawing and the. letters of reference marked thereon, to bea full, clear, and

exact descriptiomand which said drawing constitutes part of thisspecification, and represents in Figure I"; a plan view of my invention;

Figure 2 is a section through line K'L'ol fig. -1,'

r Figure 3 is a'ii'ont view of thele'vcr for keeping. the

forks from the ground and throwing the machine out hgure {is alongitudinal section of the clutch, slunving-the dlehiils of itsconstruction;

Figure ,5 is a plan view of the adjustable joint which regulates thethrow otthe forks; and

Figure is a side view of the same. a My invention relates to ,"themachines used for spreading hay, known as tedders, and j It consists ofsuch; construction and arrangement ot' the same, whereby the arms,having a stud or sup;

portal; the'lower ends," upon which the forks are hung, are pivoted orhinged to themaiu-fi-ame, so that each arm, with its fork,-actsindependently of the others, and the whole series,=with their forks,accommodate I themselves tothe surface of the ground; aiuha serics oflevers, which are also pivoted are. so connected to the main 'frame,together, and to the cranks which airs operated by the wheels,that, as;said wheels revolve, a reciprocating movement is communicated to thelevers and to'the forks, to which the said levers are also connected bymeans of rods, and the forks are,

thuscaused to make a reciprocating movement, whilethe lower end of thearmyto which each fork is attached, is moving freely upon the ground.The forks are'hung upon pivots, "and an adjustable clamp is attached tothe upper end of the forks,"which may be moved either up or downthereon, so that the rods which connect these clamps to the'levers,which are pivoted to the frame, may causefthe lower ends of thet'orks-to makca longer or" shorter s'\v eep,.as may be desirable. a p i Afoot-piece is so arranged, in connection with a lever-attached to across-bar, and with the independent arms, and'also two levers connectedby a cross-piece,

.which support said armswhen raised from the ground, that, when saidfoot-piece is pressed down to raise the arms from the ground, the saidfoot-piece strikes upon two angle-irons pivoted to the cross-bar, whichcause .therods connected to the gearing-clutch to move inward,separating the two parts of the clutch, and

is connected only at one end with throwing the machine out of gear atthe/same time that the arms are raised from the ground. That othersskilled in-the art may be able to make and use my invention, I will nowproceed to describe its constructionand mode of operation.

- In the drawing- 1) represents the main cross-bar oi the machine, amt

an and cthe frame, which is attached to the s: t id crossbar. v r

, 'Thewheels revolve rgumaxles attached to the pieces 0', and tothe'inain crossbar-D are hinged, at. cT', 1; 1c beams B, the rc'arfendsof said beams-dragging upon the ground; and these said beams are sohinged that the rearcnd of each onemay be raised from the ground toanydesired height without interfering with any of the others,- so thatall" the said beams have an independent vertical movement. 1

The studs H are attached to the rearends of the beams B, and pivoted tothe tops of these studs are the forks t, which may be formed of wire,and, at the pivot, coiled around a spindleat t.

'An' adjustable clasp, H, is attached to the top of said forks, whichconsists of two plates, 1: and 1:, which are held together by means of ascrew, :0", the rods of, thei'ork t being between them; and the backplate 1:-

has a hinge made upon the top, into which is con nected the 'rod c.

This clasp H may be adjusted to any desired height upon the topsorshort. arms of the forks t, so that their longer arms may have more orless throw, as may be desirable. j p p The rods 0 extend l'orward,'andare attached to the sides of the vibrating bars I), which are pivoted,near:

their centers, to the main cross-bar D at 17,. and the bars I) haveacentral projection, i", thereon, the ends of which are connected bymeans of the bars at. i

The vibrating bar on'each side nearest the wheel A a fork,"H, the otherandshorter end having attached with the clutch e. r

The details of the. construction o'fft-his clutch are shown more fullyin fig. 4, in which is the shaft, having the aunularvenlargemcnt 'e'.thereon, which has vertical or ratchet-teeththereon, and beyond thisenlargement is a projecting-shaft, r, extending into a socket or cavityin the piece 0. This part a has ratchet or vertical teeth nponthe endnext the part 0", and

forms the other part of the clutch, and the part a is.

attached 'firmly to, or is made in one piece with the pinion o. A

. to 0 are boxes, which serve as bearings for both parts of the clutch,and around-"the part e" is a groove, in which one end of the rod zclaspsthe part e"; and

thereto the rods, which is also-attached .-.to the smali crank 0",connected there is snfiicicnt space between the enlarged part c" and thebox 0, containing the crank-shaft 'r, to allow ofsufficici-itlongitudinal play of the shaft to cause the two parts 0 ande to become disengaged when the shalt v is moved inward from the wheel.

The other end of the rod is secured to the trainee,

a, or to a piece, a", attached to its lower side. These angle-irons havetwo arms at nearly a right angle to each other. To the end of one arm isattached the rods f, and uponthe end of the otherismadea projectiou, n.

A small spring may be placed behind the lower end of the lever It, whichis pivoted to the bar of at 2:, so that the lower end of said lever mayalways be kept :ihrowu out from the face of the bar a, as shown in Whenthe foot-board 1 is pressed down, it strikes agalust'the lower end ofthe lever h, forcing it into the position shown in dotted lines in fig.2, until the foot-board passes below the lower end of the lever, when itflies back to its position shown in black lines. Wheu'the foot-board isin this position, it presses down upon the projections 11, throwing theangle-irons n into the position shown in dotted lines in tig. 3, movingthe rods finward, and drawing the rods-z and cmnks c" inward, causingthe clutches e and e to become disengaged. The machine may then be drawnwithout operating any of the forks or other connecting parts. 4 g

The circular piece 0'', firmly secured to the wheels A, and toothed uponthe inside, engages with the teeth upon the pinion 0, and causes saidpinion and the clutches c' e and crank c to rotate, as the machine isdrawn along, when the clutches are closed.

The seat E may be attached to themaiu cross-bar by means of one or moreiron braces.

By using eight of the beams B and forks, every other fork will operatein the same direction at the same time, and by using six, the forks willoperate alike, in pairs.

The operation of the machine is as follows:

By drawing the machine, the toothed pinion and crank-c", connected bythe clutch, are caused to rotate by the toothed circle 0" and the rods0, attached to the crank and outside lever b','are made to perform avibrating movement upon its pivot, i. This movement is communicated tothe other-levers by means of the connecting barsin, and the rods 0,attached to the ends of these levers and to the forks, cause saidrot-rm) make a vibrating movement upon their pivots. The length of theforks is such that, as the rear ends of the beams B drag upon theground,the forks will throwup the hay in their movement backward.

As the beams B are hinged to the crossbar 1), their own weight keepstheir rear ends upon the ground, while they are tree to rise when comingin contact with or passing over any stones or any prominence, and are asfree to fall into any depression in thesurface, of the ground.

When'passing to and from the hay-field, or along the road, the machinemay be made tocease its operation by depressing the foot-board F, sothat the upper surface of the same shall be below the lower end of thelever 12, which will then spring out over the foot-board and secure itin that position. '1his operation of depressing the'foot-board raisesthecross-bar s, beneath the beams B, and, as it rises, it lifts thebeams, with the forks attached, from the ground into the position shownin dotted lines in fig. 2. At the same time the lower front edge of thefoot-board presses upon the projections 11, upon the angle-irons a", anddraws the part e' of the clutch inward and away from the other part a,disengaging them, and the wheels A will then roll upon the groundwithout operating the machine.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1.,The foot-piece F, levers s, and cross-bar s, in

combination with the lever h, hinged arms I3, and angle-irons n", withtheir connections, f and I, so as to raise the tedder-arms and, at thesame time, throw the clutch out of gear.

.2. The arrangement of the adjustable clamps H, constructedsubstantially as described, the rods 0, and pivoted forks t,substantially as set forth.

3. The series of levers b, pivoted to the frame 1 connected together bythe bars at, and operated by means of the cranks c and rods 0', saidlevers being connected to the forks t bythe rods 0, all arranged andoperating substantially as described.

4. The series of independent arms B, hinged, at c", to the frame I),-aud bearing at their lower ends the studs or supports H, upon which theforks are hung, all constructed and opcrz'tting substantially asdescribed.
